Histon lactylation drives HAS2 expression in gastric cancer tumorigensis after H.pylori infection

ABSTRACT: Histone lactylation, an epigenetic modification, promotes tumor growth and immune evasion in various cancers. Our study found increased pan-lysine lactylation and H3K18la in gastric tissues, linked to poor prognosis. Inhibiting glycolysis and silencing lactate dehydrogenase reduced H3K18la, boosting CD8+ T-cell activity against gastric cancer. H3K18la activated HAS2 transcription, enhancing MYC nuclear transport and PD-L1 expression..Our data provide a molecular framework for Histone lactylation in the process of gastric cancer.

Lactate-Induced H3K18 Lactylation Drives CX3CL1-Mediated Immune Cell Recruitment in Sepsis-Associated ARDS

Project description:Sepsis is characterized by lactate accumulation and immune dysfunction, but the molecular mechanisms linking lactate to chemokine expression remain unclear. Here, we investigated whether lactate regulates chemokine transcription through histone lactylation. Human peripheral blood mononuclear cells (PBMCs) were treated with lactate (LAC group) or PBS control (CON group), followed by RNA sequencing (RNA-seq) to identify differentially expressed genes. Chromatin immunoprecipitation sequencing (ChIP-seq) using H3K18la-specific antibody was performed to detect lactylation-enriched gene promoters. Integration of RNA-seq and ChIP-seq data identified CX3CL1 as a lactylation-regulated chemokine. Functional assays demonstrated that lactate-induced H3K18la promotes CX3CL1 expression, enhances PBMC migration, and facilitates T cell recruitment in vitro. In a cecal ligation and puncture (CLP)-induced sepsis-associated acute respiratory distress syndrome (ARDS) mouse model, elevated lactate increased pulmonary CX3CL1 expression and immune cell infiltration, whereas inhibition of lactate production reduced these effects. These data reveal a lactate–H3K18la–CX3CL1 axis that mediates immune cell recruitment and exacerbates sepsis-related lung injury.

Lactate and histone H3K18 lactylation are associated with metabolic control of gene expression in the retina [timecourse_CUT&Tag]

Project description:High aerobic glycolysis in retinal photoreceptors, as in cancer cells, is implicated in mitigating energy and metabolic demands. Lactate, a key product of glycolysis, is implicated in epigenetic regulation through histone lactylation in cancer. Here, we demonstrate that increased ATP production during retinal development is achieved primarily through augmented glycolysis. Histone lactylation, especially H3K18La, parallels enhanced glycolysis and its product, lactate, in developing retina and in retinal explants. Multi-omics analyses, combined with confocal imaging, reveal the localization of H3K18La near H3K27Ac in euchromatin at promoters of active retinal, especially photoreceptor, genes. H3K18La and gene expression also correspond to glucose metabolism in retinal explants. Evaluation of accessible chromatin at H3K18La promoters uncovers an enrichment of GC-rich motifs for transcription factors of SP, KMT and KLF families, among others, indicating specificity of H3K18La-mediated gene regulation. Our results highlight glycolysis/lactate/H3K18La as a regulatory axis in fine-tuning gene expression in developing and mature retina.

Nuclear GTPSCS functions as a lactyl-CoA ligase to promote histone lactylation and glioma progression

Project description:Histone lysine lactylation is a physiologically relevant epigenetic pathway that can be stimulated by the Warburg effect and hypoxia-associated L-lactate. Nevertheless, the mechanism by which cells use L-lactate to generate lactyl-CoA, the cofactor for the modification, and how this process is regulated remain unknown. Here, we report the identification of GTPSCS as a lactyl-CoA ligase using biochemistry and cell biology approaches. The mechanism of this catalytic activity was elucidated using the crystallographic structure of GTPSCS in complex with L-lactate, followed by mutagenesis experiments. GTPSCS translocates into the nucleus and interacts with p300 to form a functional lactyltransferase to elevate histone H3 lysine 18 lactylation (H3K18la). This process is dependent on not only a nuclear localization signal in the GTPSCS G1 subunit but also acetylation at the G2 subunit residue K73 (for the interaction between GTPSCS and p300). GTPSCS-p300-mediated histone H3K18la promotes glioma cell proliferation and tumor formation in mice. In addition, histone H3K18la is positively associated with glioma grade and poor prognosis in glioma patients. The LDHA-GTPSCS-lactyltransferase-histone Kla axis thus represents a signal-stimulated epigenetic pathway that mediates the downstream impact of the Warburg effect and hypoxia

Macrophage histone lactylation during ischemia induced-muscle regeneration [RNA-Seq]

Project description:After injury, muscles require fully functional macrophages to recover completely. During muscle regeneration, macrophages transition from a pro-inflammatory to a pro-restorative phenotype ensures the proper regeneration. Lactate is a crucial molecule for muscle-residing macrophage polarisation. Histone lactylation, a direct derivative of lactate, has been implicated in macrophage polarisation in vitro . In this work, we show for the first time that macrophages recruited to the muscle after ischemic injury modify their histone lactylome between 2 and 4 days post injury. Absolute histone lactylation levels increase significantly. Although subtly, also the genomic enrichment of H3K18la changes from 2 to 4 days post injury and this correlates with gene expression changes. Interestingly, we find that H3K18la genomic enrichment changes from day 2 to day 4 post injury are predictive for gene expression changes later in time, from day 4 to day 7, rather than being a reflection of past gene expression changes from day 1 to day 2. Our results suggest that histone lactylation dynamics are functionally important for the resolving action of macrophages during muscle regeneration.
